Txhawm rau xaiv txoj cai poob cable kev sib txuas lus daws teeb meem rau FTTH network yog qhov tseem ceeb heev. Cov khoom sib txuas thiab txaws, raws li ob txoj kev sib koom ua ke los sib txuas ntawm cov xaim hluav taws xob, yog dav siv ntawm FTTH xa mus. Peb txhua tus paub tias tus splice tuaj yeem muab qhov sib koom ua ke tas mus li, thaum tus txuas tau tuaj yeem ua haujlwm yooj yim los ntawm tes. Tab sis muaj cov paj lug uas hais tias koj tsis tuaj yeem muaj koj lub ncuav mog qab zib thiab noj nws ib yam nkaus, cov muab kev pabcuam yuav tsum xaiv ntawm ob. Yog li peb yuav xaiv qhov twg? Daim ntawv no yog yuav los tham txog lawv hauv cov ncauj lus kom ntxaws tham txog lawv tus kheej qhov zoo thiab qhov tsis zoo.
Cia thawj zaug mus nrog lub splice. Splice muaj peev xwm ntawm kev ntseeg tau zoo thiab tuaj yeem muab qhov muag ua tau zoo heev, kom nws tau txais kev qhuas siab rau ntau xyoo. Dab tsi ntxiv, thaum lub txuas tsis yog mated, splicing tuaj yeem tiv thaiv qhov txuas kawg-ntsej muag los ntawm cov khoom sib kis uas tuaj yeem ua rau lub qhov muag tsis pom lossis tseem ua rau lub txuas txuas mus tas li. Nws tsuas yog txo cov kev puas tsuaj no kom tsawg kawg nkaus. Lwm qhov zoo dua ntawm kev sib cais yog tias nws ua rau kev hloov pauv ntawm 250 µm poob rau cable fiber ntau rau jacketed cable.
Thiab tom qab ntawd cia peb tham txog nws qhov tsis zoo. Lub ntsiab tsis zoo ntawm nws yog qhov tsis muaj haujlwm ua haujlwm yooj yooj yim. Piv txwv li, yog tias koj xav rov kho dua qhov poob cable ntawm qhov chaw faib khoom, koj yuav tsum tshem tawm ib qho kev sib cais, rov qab ua cov fibers thiab txaws ob daim tshiab. Qhov no yuav tsum muaj tus ti teg taw los nqa cov cuab yeej splicing tshwj xeeb rau kev pauv cov neeg ua lag luam. Thiab tseem, thaum koj tab tom ua haujlwm ntawm kev xa xov ntawm qhov chaw faib khoom, koj yuav tsum ua tib zoo nrog lub fiber nyob rau hauv thaum khoov los yog tawg nws. Yog tias cov splice tau siv ntawm ONT, yuav tsum muaj chaw rau lub tais kom tuav thiab tiv thaiv cov splice. Qhov no nce ntawm ONT qhov loj me thiab qhov muaj peev xwm tus nqi.
Tsis zoo li splice, txuas tuaj yeem muab qhov ua haujlwm tau zoo nyob rau hauv uas lawv tuaj yeem tau mated thiab unmated dua, cia lawv siv rau ntau dua thiab siv dua. Thaum koj xav tau txuas cov hlua cable, koj tuaj yeem siv lub pob hluav taws xob txuas rau kev sib yuav tsis muaj lwm yam cuab yeej.
Tsis tas li, txuas tau nws tus kheej qhov tsis zoo, ib yam li txhua lub npib muaj ob sab. Qhov teeb meem loj tshaj plaws ntawm nws yog khoom siv nqi. Yog li, cov muab kev pabcuam yuav tsum hnyav cov khoom siv ntawm cov khoom sib txuas nrog rau cov peev xwm ntawm kev sib kis thiab kev puas tsuaj rau lawv qhov kev hloov pauv ntau dua thiab qis dua kev tswj hwm kev siv nyiaj.
Los ntawm kev txheeb xyuas saum toj no, tam sim no peb tuaj yeem kos lub xaus lus. Kev sib faib tau zoo dua rau qhov tsis muaj cov phiajcim fiber ntau, xws li lub tiaj nyom ntsuab lossis daim ntawv thov kev tsim kho tshiab. Thaum lub tshuab txuas tuaj yeem yoog raws ob qho tib si rau ntawm ntug kev thiab hauv tsev vim nws tuaj yeem ntsaws thiab tshem tawm ntau zaus.
Nyob rau hauv lo lus, poob cable kev sib txuas lus daws teeb meem yog ib qho tseem ceeb hauv FTTH network uas koj yuav tsum ua tib zoo saib thaum koj xaiv txoj hauv kev los ua qhov sib txuas. Txoj kev xaiv uas zoo yuav pab koj txuag nqi thiab ua haujlwm tau zoo dua qub. Tab sis txawm hais tias koj xav tau splicer lossis cov txuas, koj tuaj yeem pom nws hauv FOCC.
